442 results about "Desertification" patented technology

Desertification is a type of land degradation in which a relatively dry area of land becomes a desert, typically losing its bodies of water as well as vegetation and wildlife. It is caused by a variety of factors, such as through climate change (particularly the current global warming) and through the overexploitation of soil through human activity. When deserts appear automatically over the natural course of a planet's life cycle, then it can be called a natural phenomenon; however, when deserts emerge due to the rampant and unchecked depletion of nutrients in soil that are essential for it to remain arable, then a virtual "soil death" can be spoken of, which traces its cause back to human overexploitation. Desertification is a significant global ecological and environmental problem with far reaching consequences on socio-economic and political conditions.

Wind prevention and sand fixation equipment in land reclamation

The utility model provides wind prevention and sand fixation equipment in land reclamation, which relates to the technical field of wind prevention and sand fixation equipment and comprises a first shell, a third shell fixedly connected to the top of the first shell, a supporting plate fixedly connected to one side of the third shell, a telescopic rod fixedly connected to the bottom of the supporting plate, and a fourth shell fixedly connected to the bottom of the telescopic rod. A second motor is fixedly connected to one side of the inner wall of the fourth shell, an extrusion piece is fixedly connected to the output end of the second motor, a threaded rod is rotationally connected to the upper surface of the fourth shell and is in threaded connection with the supporting plate, and a handle is fixedly connected to the upper surface of the threaded rod. The height of the extrusion sheet can be adjusted according to the land desertification degree, and the flexibility and practicability of the device are improved; straw slides down to the ground along the first auxiliary plate to be evenly arranged, and the situation that the density of the straw around the straw checks is uneven, so that the stability of the straw checks is affected, and the whole straw checks are unstable in structure is avoided.
